What’s the difference between AM, A1, and CBT licences in the UK?
TL;DR: CBT is basic training that lets you ride with L‑plates for two years. AM is the moped category (usually up to 50cc, ~28mph). A1 is the 125cc light‑motorcycle licence; pass the tests to remove L‑plate limits and carry a passenger.
Key points
- CBT: a one‑day course — not a full licence; required for most new riders.
- AM (moped): typically up to 50cc; 16‑year‑olds after CBT.
- A1: up to 125cc / 11kW; available from age 17 with theory + practical tests.
- L‑plate limits: no pillion, no motorways — removed once you hold A1 (or higher).
- Renew or progress: CBT expires after two years if you don’t upgrade.
Short explainer
Think of CBT as your entry ticket. It proves you’ve been trained and can ride with L‑plates, but it isn’t a licence in itself.
AM is the moped entitlement. With CBT at 16, you can ride an AM‑class moped. At 17, you can move to A1 machines (up to 125cc / 11kW).
A1 is a full licence category. Pass your theory and practical tests on a 125 to remove L‑plates, carry a passenger, and ride on all appropriate roads (still not powerful enough for A2/A machines).
Local note: Licence checks at Central Bikes; test rides by appointment.
